Dear All,
Please help with this issue am facing with the network.
Network diagram is attached.
We are taking hosted contact center service from service provider.Connectivit is over MPLS.Cisco 881 is the CPE router.We are using our own LAN ip pool with default gateway to L3 switch interface IP.
LAN IP pool is 10.93.203.0/24 which is nated with service providers IP block 172.17.241.0/25 in the CPE router(becasue SP allows only this block to talk to their platform). Between CPE 881 and L3 switch we have configured first 2 IPs for service provider block.Detailed config is given below.
We are facing problem as router is hanging up interminttently in 3-4 days,if we reboot or clear the cache , service is back and running.Please help iwth your suggestions.
